“…This size reduction is evidenced by a prominent single peak in the rGO/SrGO hybrid dope, indicative of a uniform particle distribution in the lower range of 0.1 µm, in contrast to the varied peaks observed in the rGO dope. This uniformity is attributed to the 2-D structure of rGO, which provides surfaces for re-stacking, while the 1-D structure of SrGO offers a smaller surface area, effectively limiting particle size growth in the dope [22,23]. As a result, the rGO/SrGO hybrid dope demonstrates enhanced dispersion stability compared to the rGO dope, highlighting its potential for e cient use in wetspinning applications.…”

In the burgeoning field of flexible energy storage, creating resilient and efficient supercapacitors suitable for integration into wearable technology remains a formidable challenge. This paper introduces the hybrid fiber supercapacitors based on the reduced graphene oxide (rGO) and the scrolled reduced graphene oxide (SrGO). The unique 1-D morphology of SrGO addresses the limited dispersibility of graphene components, benefiting the wet-spinning process and performance of supercapacitor application. The SrGO provides hierarchical pore structures to rGO/SrGO hybrid fiber composed of the open pores of SrGO and the interconnected pores between rGO and SrGO. This structural enhancement translates into exceptional electrochemical attributes, including increased specific capacitance and electoral conductivity, outperforming standard graphene-based fibers. Furthermore, we demonstrate the mechanical robustness of these hybrid fibers, maintaining their electrochemical integrity under dynamic bending conditions, a breakthrough feature for wearable applications. The successful interlacing of these supercapacitors into functional textiles, offering versatility in energy storage parameters, represents a significant advancement in smart textiles.

In this work, an improved wet spinning method was proposed to prepare high-tensile-strength carrageenan fibers by pre-crosslinking process. Pre-crosslinking was achieved by adding a small amount of Al3+ ions into the spinning solution. The properties of the carrageenan spinning solution were analyzed by polarizing microscope, dynamic light scattering, and viscosity, the results showed that the modified spinning solution pre-crosslinked with Al3+ ions was orderly and high-viscosity, and the average particle size of the spinning solution was increased. The properties of the carrageenan fibers were characterized using scanning electron microscope, Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy, X-ray photoelectron spectroscopy, and tensile tests. The results showed that the new carrageenan fibers were formed by coordination and ionic bonds between Al3+, –OH and sulfate groups. The tensile strength was up to 1.77 cN/dtex of Al-3.0/CAF (the best of newly prepared carrageenan fiber in this work), which is the highest strength carrageenan fiber prepared at present. Compared with the traditional process, this method reduced the concentration of Al3+ ions in coagulation bath and stretch bath, thus saving the production cost and protecting the environment.
